ELECTRIC BELT.

SPECIFICATION forming part of Letters Patent No. 623,953, dated April 25, 1899.

Application filed September 13, 1898. Serial No. 690,897. (No model.)

To all whont it may concern:

Be it known that I, WARREN P. FREEMAN, a citizen of the United States of America, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Electric Belts, of which the following is a specification, reference being had to the accompanyingdrawings, forming part of the same, in which Figure 1 is a perspective view of an electric belt embodying my invention, portions of the lining at the back being removed to more clearly exhibit the arrangement of elements. Fig. 2 is a face view of a portion of the sustaining-strip,showing several elements in position. Fig. 3 is a sectional View of those parts shown in Fig. 2, taken on line 3 3 of said Fig. 2. Fig. 4 is a perspective view of one form of element. Fig. 5 is a similar view of another form of element. Fig. 6 shows what may be termed a reversion of one of the parts, whereby the elements are strung on instead of passed through the supporting strip; and Fig. 7 shows a. form of element adapted to be thus strung on the supportingstrip.

My invention relates to electric belts; and it consists especially in the arrangement of the elements, as well as other details, whereby I produce a very effective belt in a very simple and economical manner.

S is the supporting-strip, of which I may employ two, each slightly less than half the length of the belt or more, though one continuous piece of the full length will answer. At suitable intervals the supporting-strip, which is preferably made of open-mesh cloth, is provided with slits or openings 8.

E E are ,the elements, E being the form I prefer to employ for pole-pieces and E the preferable form for the other element members of the belt. As will be noticed, they have what I may term a dumb-bell or H form or a combination of parts of both said formsthat is, there are two enlarged ends and a narrower neck N, which is also preferably nicked, as at n. They are arranged as follows Taking one elementsay of copper' I turn over one end 0 of the enlarged part, as shown in dotted lines in Fig. 4, and, entering the other end 0 in a slit 8, pass the element to place and then flatten end 0 out again, when the element will lie with one enlarged port-ion on one side of the strip and the other enlarged portion on the opposite side of the strip. The material at the ends of the slit will enter the notches, and thus the element will be held from displacement. I next take an element of the opposite charactersay zincand place it in the next slit .9 in a similar manner, the size of the elements and the separation of the slits (one from the next) being so proportioned that the plate 2 e of the one element will overlap the plate 0 c of the other element and plate 0 c of said other element will overlap plate 2 z of the preceding element. This, as is manifest, could be done equally well if the said plates were round or of many other forms instead of rectangular. In each case the material of the supporting-strip lies between the overlapping plates of the respective elements. In such manner I continue to the places where I desire the poles of the belt to bein the belt shown at the ends of the belt and at points nearly one-half around. The poles P are negative or positive, as may be desired, according to the particular use to which the belt is to be put, and they are covered by the material of the supporting-strip, as shown at the back of the belt, or bare, as may be desired. In the latter case I prefer to silverplate them to prevent the corrosion which contact with the body might otherwise cause. The connecting-link L at the front may or may not be of conducting material, as may be found desirable. Having thus constructed and arranged these parts, I then cover them outside and inside, except the poles, with sheathing-strips S S of any desired material, preferably stitched firmly together, and with the elements and supporting-strip between, by a row of stitching at each edge, as this assists in holding the elements in place. Other elements than copper and zinc may be used.

Instead of inserting the elements in the supporting-strip, as ,is manifest, I might string them upon it, as clearly shown in Fig. 6, the slits s in such case being made'in the elements and the notches n in the supportingstrip if notches are used.

By this construction I produce a belt of considerable power which is very simple and readily and quickly constructed or repaired at a very low cost.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. An electric belt composed of a supporting-strip and a series of elements of diverse character having enlarged ends and narrower connecting portions inserted in slits in the supporting-strip and arranged with one plate or end of one element overlapping a plate or end of a diverse element on the opposite side of the supportiug-strip, all substantially as set forth.

2. An electric belt composed of a supporting-strip and a series of elements of diverse character having enlarged ends and narrower connecting portions inserted in slits in the supporting-strip and arranged with one plate or end of one element overlapping a plate or end of a diverse element on the opposite side of the supporting-strip, the connecting portion of said elements being provided with notches into which the supporting-strip may enter, all substantially as set forth. v

3. An electric belt composed of a supporting-strip and a series of elements of diverse character having enlarged ends and narrower connecting portions inserted in slits in the supporting-strip and arranged with one plate or end of one element overlapping a plate or end of a diverse element on the opposite side of the supporting-strip, and sheathing'strips inclosing said elements and said supportingstrip, all substantially as set forth.

1-. An electric belt composed of a supporting-strip and a series of elements of diverse character having enlarged ends and narrower connecting portions inserted in slits in the supporting-stripand arranged with one plate or end of one element overlapping a plate or end of a diverse elcment on the opposite side of the supportingstrip, and sheathing-strips inclosing said elements and said supportingstrip and stitched firmly together at or near each side edge, all substantially as set forth.

5. An electric belt composed of a supporting-strip and a series of elements of diverse character havin enlarged ends and narrower connecting portions inserted in slits in the supporting-strip and arranged with one plate or end of one element overlapping a plate or end of a diverse element on the opposite side of a supporting-strip, together with two or more pole-pieees,all substantially as set forth.

(3. An element for an electric belt, having enlarged ends and a narrower connectingpiece, all substantially as described, and adapted to be-inserted in a supporting-strip and to lie partly on one side and partly on the other side of said strip and to have its respective ends overlap a preceding and a suececding plate of diverse character, all substantially as set forth.

7. An element for an electric belt, having enlarged ends and a narrower connectingpiece, provided with one or more notches, all substantially as described, and adapted to be inserted in a supporting-strip and to lie partly on one side and partly on the other side of said strip and to have its respective ends overlap a preceding and a succeeding plate of diverse character, all substantially as set forth.

8. An electric belt composed of a supporting-strip and a series of elements, combined with said strip in sequence as set forth, whereby one part of the element is on one side of said strip and another part on the opposite side of said strip, said parts being arranged to respectively overlap the proximate parts of the adjacent elements and being separated from said proximate parts by the intervening portions of the supporting-strip, all substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 9th day of August, 1898.
